Eight fast-growing wildfires in Colorado are burning out of control.<br/> <br />One of these is threatening a popular summer campground beneath Pikes Peak, whose vistas helped inspire the patriotic tune "America the Beautiful".<br/> <br />The blaze in the Pike National Forest, known as the Waldo Canyon Fire, is only two miles from the base of the 14,115 foot peak - billed as the most visited mountain in North America.<br/> <br />Colorado governor John Hickenlooper said wildfires can be extremely difficult to beat.<br/> <br />(SOUNDBITE) (English) COLORADO GOVERNOR JOHN HICKENLOOPER SAYING:<br/> <br />"The problem can be that the fire can smoulder in the trunk of a tree for a day, two days, up to five or six days and then with a strong wind, burst into flames. So it's challenging."<br/> <br />The Waldo Canyon Fire has consumed about 2,500 acres since Saturday and triggered evacuation orders for 11,000 people from Colorado Springs and nearby towns.<br/> <br />Travis Brecher, Reuters
